Crackling noise from PSU

unplanned bacon · Aug 12, 2014

It's a brand new Antec unit. I noticed when I went to plug it on it makes a crackling noise. My Corsair unit never did this. It was on at the plug when I went to do this. Is my PSU safe?

Not normal RMA it before something bad happens.

:/ spent all that time wiring it up. I know when my laptop started doing that it was beaten and broken so I stopped using it immediately

Not worth the risk of damage to other components.

True, I'm just thinking all that time. Potentially a fire hazard so it's also been unplugged. My rig is down for now

Sorry to hear that , hope you get a fast replacement.

Was potentially a two week wait for a new unit if I wanted a replacement from that seller or not wanted to fit the Corsair back in. Returning it for refund and having to pay more for the same item from another seller :/

Great choice , hopefully you get a new unit soon.

Should have a new one in the next 3 days. Back to using my laptop and it's just not the same, so slow and some stuff doesn't work. Can say goodbye to Battlefield 4 game time. Just when it had achieved high end/beast status D:

EDIT: I meant 3 - 5 days

Only a few days to wait!! . Not bad!

Can't take this computer anymore (the laptop)! Just so slow and constantly hanging and locking up. Takes an hour just to do a simple task (whereas on my gaming PC I'll have done 60 tasks in the same amount of time). Seriously the gaming PC can have Battlefield 4 running and leave everything else open at the same time and the performance barely takes a hit (never got to try with the 780, PSU gave out too soon), whereas this one struggles running just Chrome and an install process. Missed delivery of my new one today as I was working and didn't expect them to deliver a day early, thought they'd miss and then get the weekend instead. As it is, it will be down over the weekend as well till Monday, just when I had just upgraded too (putting the Corsair back in for a few days would be quite a bit of hassle, but I might just do it) :/

My gaming rig has spoiled me (actually taken over my laptop's role of work computer as well because it did it so much better) :'(

Can't wait for Monday

The short wait is on.

Two hours later my new PSU is in. Seems to do a similar sort of thing to the old one, but barely audible. I've seen this sort of behaviour with light switches where there's poor contact. The noise is at the point where the kettle cable makes contact with the pins (only happens if the plug socket is on and the PSU is on). Strictly speaking I am plugging it in the wrong way when I do that, because the PSU should be off and the wall socket should be off then I connect and then power on. Really don't want to have to be doing the same thing in a week's time :/

Missed this machine man, it's just so so quick and I can ALT and Tab out of games really fast, unlike on my laptop which didn't like it. The graphics are just so good

On the subject of graphics, as long as the GPU has two green lights then it's all good, because I had a red light when I powered on which turned out to be a loose cable. How do I get my front fan to quieten down, a week ago this thing was dead silent, but now (I've changed my routing and the spare cabling sits cable tied in the spare space in the hard drive cage which does disrupt front case fan air flow a bit, but they had nowhere else to go seeing as I managed to use one less cable

). Granted the thing feels like an ice box from the outside (obviously not as cold) like when it was brand new (thing could cool the area around it as well) so my cooling is working

EDIT: I stand corrected. I just did a quick test where I let it fully discharge and recreated the conditions, no noise. Old one was faulty

Hi, for anything you are connecting to a power cord, it should be turned off. It seems like you had the PSU on when you plugged in the power cord. Naturally you get then crackling noise. Always have any device turned off when connecting a power cord. What you are doing is damaging components due to a high inrush current being established immediately.

I should probably stop doing that. I don't often do that, I just so happened to that day. I figured it was what I did that caused that. Now if only I could find out how to make my case fan silent again like it was last week

unplanned bacon · Aug 20, 2014

I've managed to reduce the number of cable I use by 1 and improved my cable management a bit

Getting better at this. But to do it, the 6+2 and the 6 pin for my GPU had to do some unnatural bending because they are really stiff. I'd rather put them under a bit of stress against the case than stress my GPU connections though. Operational volume is sounding better now, but not dead silent yet. Need some compressed air or something to clean out the dust. The hottest thing in there now is my CPU, idling at 40 whereas everything else is 30 or lower. Ambient is 28 (judging by the board's temps)
